Gemfan 18x10x3 Glass Fibre Nylon 3-Blade Propeller, Black (CW/CCW Pair)

A matched pair of Gemfan 18x10x3 three-blade propellers in black glass fibre reinforced nylon, made for heavy-lift multirotors of about 1300 mm wheelbase. Each pack holds one clockwise and one counter-clockwise prop, so a quadcopter needs two packs and a hexacopter three.

Key features

• 10-inch pitch on an 18-inch disc; the third blade adds thrust within the same diameter, at a small efficiency cost against a two-blade prop

• Glass fibre reinforced nylon keeps the blades stiff under heavy load

• 6 mm centre hole, adapter-compatible for other motor shafts

• Rated for 5330-class motors on quadcopters of 11-13 kg take-off weight

• 119.3 g per propeller
